| dc.description | Herbicides are essential for increasing agricultural productivity, but present environmental and health challenges. This research emphasizes understanding their interaction in the soil and conserving soil as a key resource for sustainable agriculture, addressing water pollution and resistance in weeds by characterizing herbicide dynamics. The research focuses on understanding the dynamics of herbicides in the soil to minimize their environmental impact and improve their effectiveness in weed control. Specific objectives address half-life, degradation, influence on soil biodiversity and weed resistance. The theoretical framework provides information on weed types, their impact on agriculture and herbicide composition. The results show that soil organic amendments diversely affect herbicide dynamics, with organic carbon increasing its persistence in the superficial layers and chemical oxygen demand (COD) increasing its release in deeper layers. Furthermore, the degradation of herbicides such as 2,4-D and MCPA is mainly microbial in rice cultivation soils, reducing groundwater contamination, although herbicides such as glyphosate negatively affect the soil microbiota and beneficial organisms such as earthworms. , which can impact soil health and nutrient availability. | es_ES |

| dc.description.abstract | Los herbicidas son fundamentales para aumentar la productividad agrícola, pero presentan desafíos ambientales y de salud. Esta investigación enfatiza comprender su interacción en el suelo y conservar el suelo como recurso clave para una agricultura sostenible, abordando la contaminación del agua y la resistencia en malezas mediante la caracterización de la dinámica de los herbicidas. La investigación se enfoca en comprender la dinámica de los herbicidas en el suelo para minimizar su impacto ambiental y mejorar su eficacia en el control de malezas. Los objetivos específicos abordan la vida media, degradación, influencia en la biodiversidad del suelo y la resistencia de malezas. El marco teórico proporciona información sobre tipos de malezas, su impacto en la agricultura y la composición de herbicidas. Los resultados muestran que las enmiendas orgánicas del suelo afectan de manera diversa la dinámica de los herbicidas, con el carbono orgánico aumentando su persistencia en las capas superficiales y la demanda química de oxígeno (DQO) incrementando su liberación en capas más profundas. Además, la degradación de herbicidas como el 2,4-D y el MCPA es principalmente microbiana en suelos de cultivo de arroz, reduciendo la contaminación del agua subterránea, aunque herbicidas como el glifosato afectan negativamente el microbiota del suelo y organismos beneficiosos como las lombrices, lo que puede impactar la salud y la disponibilidad de nutrientes del suelo. | es_ES |
